[All Certified Data Engineer Professional Questions]

A data architect has designed a system in which two Structured Streaming jobs will concurrently write to a single bronze Delta table. Each job is subscribing to a different topic from an Apache Kafka source, but they will write data with the same schema. To keep the directory structure simple, a data engineer has decided to nest a checkpoint directory to be shared by both streams.

The proposed directory structure is displayed below:



Which statement describes whether this checkpoint directory structure is valid for the given scenario and why?

  • A. No; Delta Lake manages streaming checkpoints in the transaction log.
  • B. Yes; both of the streams can share a single checkpoint directory.
  • C. No; only one stream can write to a Delta Lake table.
  • D. No; each of the streams needs to have its own checkpoint directory.
